Overview of this book

C++ has evolved over the years and the latest release – C++20 – is now available. Since C++11, C++ has been constantly enhancing the language feature set. With the new version, you’ll explore an array of features such as concepts, modules, ranges, and coroutines. This book will be your guide to learning the intricacies of the language, techniques, C++ tools, and the new features introduced in C++20, while also helping you apply these when building modern and resilient software. You’ll start by exploring the latest features of C++, and then move on to advanced techniques such as multithreading, concurrency, debugging, monitoring, and high-performance programming. The book will delve into object-oriented programming principles and the C++ Standard Template Library, and even show you how to create custom templates. After this, you’ll learn about different approaches such as test-driven development (TDD), behavior-driven development (BDD), and domain-driven design (DDD), before taking a look at the coding best practices and design patterns essential for building professional-grade applications. Toward the end of the book, you will gain useful insights into the recent C++ advancements in AI and machine learning. By the end of this C++ programming book, you’ll have gained expertise in real-world application development, including the process of designing complex software.

Understanding cross-platform GUI programming

Each OS has its own API. It relates to the GUI in particular. When companies plan to design, implement, and ship desktop applications, they should decide what platform to focus on. A team of developers working on one platform will spend almost the same amount of time writing the same application for the other platform. The biggest reason for this is the different approaches and APIs provided by OS. The complexity of the API may also play a big role in implementing applications on time. For example, the following snippet from the official documentation shows how to create a button in Windows using C++:

HWND hwndButton = CreateWindow(
  L"BUTTON", // Predefined class; Unicode assumed      
  L"OK", // Button text      
  WS_TABSTOP | WS_VISIBLE | WS_CHILD | BS_DEFPUSHBUTTON, // Styles      
  10, // x position      
  10...
